It’s not like the Bible was translated to English until centuries later when England became a thing. You’re complaining about a letter in an alphabet that wasn’t relevant yet.
Hebrew: יְהוֹשֻׁעַ יֵשׁוּעַ
Greek: Ἰησοῦς
Aramaic: Iēsous
Latin (maybe you’ll like this more?): IESVS
See how we get there?
Haha all good. That actually inspired me to slap this together. If you read the text maybe this will make sense.
